The National Instruments NB-A2000 (for Macintosh II NuBus) board can capture multiple frames through DSP operations. During posttrigger operation, buffer chaining is used to automatically fill the contiguous buffer. A buffer chaining or TC interrupt notifies the driver when each frame has been acquired. When pretrigger data is also collected, each frame buffer is filled circularly using autoinitialization, as previously described. However, buffer chaining and autoinitialization cannot be used together. The NB-A2000 interrupt the driver when the current frame has been acquired, and the DMA controller is left in autoinitialize mode but is reprogrammed with the base address of the next buffer. The NB-A2000 is designed so that the driver must re-enable the board to respond to the next trigger. The driver can then ensure that the DMA controller is completely programmed before the next frame is acquired.
